Reasons for revisiting include active monitoring of content, verification of information, regular use of online services, and reoccurring tasks. Browsers support for revisitation is mainly focused on frequently and recently visited pages. In this paper we present a dynamic browser toolbar that provides recommendations beyond these usual suspects, balancing diversity and relevance. The recommendation method used is a combination of ranking and propagation methods. Experimental outcomes show that this algorithm performs significantly better than the baseline method. Further experiments address the question whether it is more appropriate to recommend specific pages or rather (portal pages of) Web sites. We conducted two user studies with a dynamic toolbar that relies on our recommendation algorithm. In this context, the outcomes confirm that users appreciate and use the contextual recommendations provided by the toolbar.","PeriodicalId":91270,"journal":{"name":"HT ... : the proceedings of the ...

Given the scale of the potential result sets, how does one identify the 'best' or 'right' set of items? We explore a solution that aligns characteristics of the information space, including specific content attributes and the information diversity of the results set, with measurements of human information processing, including engagement and recognition memory. Using Twitter as a test bed, we propose a greedy iterative clustering technique for selecting a set of items on a given topic that matches a specified level of diversity.\u0000 In a user study, we show that our proposed method yields sets of items that were, on balance, more engaging, better remembered, and rated as more interesting and informative compared to baseline techniques. Additionally, diversity indeed seemed to be important to participants in the study in the consumption of content. However as a rather surprising result, we also observe that content was perceived to be more relevant when it was highly homogeneous or highly heterogeneous. In this light, implications for the selection and evaluation of topic-centric item sets in social media contexts are discussed.","PeriodicalId":91270,"journal":{"name":"HT ... : the proceedings of the ...

In 1969, IBM wanted to show the system at a conference, and Nelson gained permission to use Vladimir Nabokov's highly unconventional and hypertextual novel, Pale Fire (1962) as a technical demonstration of hypertext's potential. Unfortunately, the idea was dismissed in favor of a more technical-looking presentation, and thus was never demonstrated publicly. This paper re-considers Pale Fire's position in hypertext history, and posits that if it was used in this early hypertext demonstration, it would have been the 'father of all hypertext demonstrations' to complement Douglas Engelbart's 'Mother of All Demos' in 1968. In order to demonstrate the significance of Pale Fire's hypertextuality and Nelson's ambitions to use it, this paper will explore its hypertextual structure, the implication thereof for the novel and evaluate its success as a hypertext compared to electronic systems.","PeriodicalId":91270,"journal":{"name":"HT ... : the proceedings of the ...

Macroscopic analysis of massive datasets raises interesting observations of patterns in online social processes. But working at a large scale has its own limitations, since it typically doesn't allow for interpretations on a microscopic level. We examine how different types of individual behavior affect the decisions of friends in a network. We begin with the problem of detecting social influence in a social system. Then we investigate the causality between individual behavior and social influence by observing the diffusion of an innovation among social peers. Are more active users more influential? Are more credible users more influential? Bridging this gap and finding points where the macroscopic and microscopic worlds converge contributes to better interpretations of the mechanisms of spreading of ideas and behaviors in networks and offer design opportunities for online social systems.","PeriodicalId":91270,"journal":{"name":"HT ... : the proceedings of the ...

In the context of social events, end-users record video material with their personal cameras and upload the content to a common repository. Video narrative techniques, implemented using Narrative Structure Language (NSL) and ShapeShifting Media, are employed to automatically generate movies recounting the event. Such movies are personalized according to the preferences expressed by each individual end-user, for each individual viewing. This paper describes our prototype narrative system, MyVideos, deployed as a web application, and reports on its evaluation for one specific use case: assembling stories of a school concert by parents, relatives and friends. The evaluations carried out through focus groups, interviews and field trials, in the Netherlands and UK, provided validating results and further insights into this approach.","PeriodicalId":91270,"journal":{"name":"HT ... : the proceedings of the ...
